Definitions
- compositions/devices for treating diseases of the oral cavity, which compositions/devices are placed in or around the periodontal pocket.
- the invention also relates to methods of using the compositions/devices in humans and lower animals suffering from such diseases.
- Periodontal disease for example, is a major cause of tooth loss in adults. Tooth loss from periodontal disease is a significant problem beginning at age 35, but even by age 15 it is estimated that about 4 out of 5 persons already have gingivitis and 4 out of 10 have periodontitis.
- the present inventor has discovered that using polypropenoic acid as the material forming the composition/device allows for efficient/good devices to be formed.
- This invention utilizing highly swell able polymer eliminates such problems. Once a product of this invention is placed in periodontal cavity, the polymer swells, expands, and reaches narrow crevices and furcations of the treated cavity, carrying active agent throughout the cavity. This provides most desirable efficacy at treatment site.
- the present invention relates to compositions/devices and methods for treating diseases of the oral cavity by inserting the compositions/devices around or into the periodontal pocket of humans and lower animals.
- the compositions/devices comprise polypropenoic acid and an agent providing relief of diseases of the oral cavity such as periodontal disease.
- compositions/devices of this invention are described below.
- the polymer used in the present compositions is referred as super absorbent polymer and is defined as polypropenoic acid.
- the material is a polyacrylic acid which is lightly crosslinked with an agent such as divinyl glycol, trimethylpropane triacrylate and polyallyl sucrose. These materials are provided as Dry Tech 512 by Dow Chemical Company, Aqualac-CA by Nippon Shokubai and NALCO-1181 by Nalco Chemicals. Other materials related to the above include Polycarbophil by B. F. Goodrich Company.
- a preferred material is Dry Tech-512 which is polyacrylic acid crosslinked with 0.004 mole percent of trimethylpropane triacrylate.
- the carboxylic groups can be neutralized with, for example, a sodium base to an extent of 75% or more.
- a most preferred polymer useful in the present invention has very high, nearly infinite molecular weight in its crosslinked form which is estimated to be 2 million to 10 million or even higher.
- Unit segments of crosslinked polymer have a range of number average molecular weight from about 50,000 to about 1 million.
- the polymer is used in the present compositions at a level of from about 1% to about 99%, preferably from about 10% to about 75%, most preferably from about 20% to about 50%.
- the drugs useful for use in the present compositions/devices are varied and many and include any agent which provides treatment of the disease.
- Some therapeutic agents which are amenable to delivery by this means and are potentially of value for periodontal therapy include (but are not limited to) antimicrobial/antibacterial agents such as iodine, sulfonamides, mercurials, bisbiguanides, or phenolics; antibiotics such as tetracycline, neomycin, kanamycin, metronidazole, or clindamycin; antiinflammatory agents such as aspirin, naproxen, ibuprofen, flurbiprofen, indomethacin, eugenol, or hydrocortisone; immune-suppressive or stimulatory agents such as methotrexate or levamasole; dentinal desensitizing agents such as strontium chloride or sodium fluoride; odor masking agents such as peppermint oil or chlorphyll; immune reagents such as
- the drug active is used at a level of from about 1% to about 99%, preferably from about 5% to about 75%, most preferably from about 10% to about 50% of the compositions/devices.
- the compositions/devices are designed to release drug at a rate to provide concentration of from about 10 ⁇ g to about 2000 ⁇ g, preferably from about 50 ⁇ g to about 1000 ⁇ g, most preferably from about 100 ⁇ g to about 500 ⁇ g per milliliter of the gingival crevicular fluid of a treated periodontal pocket. Desired release rates can be achieved by altering ratios of components in a composition.
- compositions/devices of the present invention may include a variety of optional components.
- Such components include, but are not limited to, surfactants, other polymers, viscosity controlling agents, complexing agents, antioxidants, gums such as guar gum, waxes/oils such as castor wax, castor oil, glycerol, dibutyl phthalate and ethyl sebacate as well as many others.
- the additional polymer may include a number of polymers such as methyl cellulose, polycaprolactone and polylactide.
- a particularly preferred polymer is a copolymer of lactide and glycolide. Lactide monomeric species preferably comprise 15% to about 85%, most preferably from about 35% to about 65%, of the polymers while glycolide monomers comprise from about 15% to about 85% of the polymer, preferably from about 35% to about 65% on a molar basis.
- the molecular weight lies in the range of from about 1000 to about 120,000 (number average).
- these optional components comprise from about 0.1% to about 50%, preferably from about 0.5% to about 25% of the total composition/device.
- compositions/devices of this invention are disclosed in the Examples.
- composition/device of the present invention Weight % Tetracycline hydrochloride 50 Polypropenoic acid 22.7 Poly(lactyl-co-glycolide)/50:50 copolymer 22.7 Propylene Carbonate 4.6
- the above composition can be prepared in a number of different ways.
- One way is as follows: Polymer is charged into 110°C, electrically heated mixer, equipped with high shear Sigma type rotor blades. Propylene carbonate is added and mixed into the polymer. The drug is added and mixed until uniform. The drug polymer blend is removed for further processing into desired size and shaped devices.
- compositions/devices of the invention of this application are inserted into or around the periodontal pocket or gingival region, and are administered in the form of a particle, film or sheet.
- the size, shape, and thickness can be changed according to the condition of the periodontal disease to be treated and they are not particularly critical. Ordinarily, the size, shape, and thickness are changed according to the size of the periodontal pocket of the patient or the condition of the gingiva.
- the devices may be for example of a size such that the thickness is in the range of 0.01 to 2mm, preferably from about 0.1 to about 1mm; the width in the range of 0.1 to about 5mm, preferably from about 0.2 to about 4mm; and the length in the range of from about 1 to about 15mm, preferably from about 3 to about 10mm.
- Chlorhexidine acetate 40 Polypropenoic acid 35 Methyl Cellulose 20 Glycerol monostearate 5
- composition/device representative of the present invention Wt. % Metronidazole 40 Polypropenoic acid 30 Polycaprolactone 25 Pluronic F-68 5
